Turkey has a very diverse culture that is a blend of various elements of the Oguz Turkic, Anatolian, Ottoman (which was itself a continuation of both Greco-Roman and Islamic cultures) and Western culture and traditions, which started with the Westernization of the Ottoman Empire and still continues today. This mix originally began as a result of the encounter of Turks and their culture with those of the peoples who were in their path during their migration from Central Asia to the West. As Turkey successfully transformed from the religion-based former Ottoman Empire into a modern nation-state with a very strong separation of state and religion, an increase in the methods of artistic expression followed. During the first years of the republic, the government invested a large amount of resources into fine arts; such as museums, theatres, opera houses and architecture. Diverse historical factors play important roles in defining the modern Turkish identity. Turkish culture is a product of efforts to be a "modern" Western state, while maintaining traditional religious and historical values.Turkish music and literature form great examples of such a mix of cultural influences, which were a result of the interaction between the Ottoman Empire and the Islamic world along with Europe, thus contributing to a blend of Turkic, Islamic and European traditions in modern-day Turkish music and literary arts. Turkish literature was heavily influenced by Persian and Arabic literature during most of the Ottoman era, though towards the end of the Ottoman Empire, particularly after the Tanzimat period, the effect of both Turkish folk and European literary traditions became increasingly felt. The mix of cultural influences is dramatized, for example, in the form of the "new symbols [of] the clash and interlacing of cultures" enacted in the works of Orhan Pamuk, winner of the 2006 Nobel Prize in Literature.Architectural elements found in Turkey are also testaments to the unique mix of traditions that have influenced the region over the centuries. In addition to the traditional Byzantine elements present in numerous parts of Turkey, many artifacts of the later Ottoman architecture, with its exquisite blend of local and Islamic traditions, are to be found throughout the country, as well as in many former territories of the Ottoman Empire. Sinan is widely regarded as the greatest architect of the classical period in Ottoman architecture. Since the 18th century, Turkish architecture has been increasingly influenced by Western styles, and this can be particularly seen in Istanbul where buildings like Dolmabahçe and Çiragan Palaces are juxtaposed next to numerous modern skyscrapers, all of them representing different traditions.
